Persistence of leading‑order KKLT de Sitter vacua to all orders in string expansions

Ascertain whether KKLT candidate de Sitter vacua constructed at leading order in the α′ and string‑loop expansions of type IIB Calabi–Yau orientifold flux compactifications remain de Sitter solutions when all higher‑order corrections in these expansions are included.

Background

The authors present de Sitter vacua of a leading‑order effective theory that includes all α′ corrections at string tree level but omits string-loop effects and subleading corrections to the anti‑D3‑brane potential.

They explicitly state that it is not yet established whether such vacua persist as full solutions of string theory when all corrections are taken into account.
